VENETIAN BLIND MOUNTING Filed Feb. 24, 195e 35M l l ff I J2 jf mi im* 'Patented Feb. 23, 1937 PATENT OFFICE l vENEriAN BLIND MOUNTING Ralph' T.

more particularly to a releasable mounting for the header bar thereof. l

It is the object of my invention to provide a simple, inexpensive, and reliable releasable mounting to support the header bar of a Venetian blind, so that such header bar and with it the Venetian blind as a whole may readily be removed and replaced, as for.. cleaning and assembling and repairing either the Venetian blind or thel adjacent window or frame,

The accompanying drawingillustrates my in vention. In such drawing: Fig. l is a front elevation of the upper part ofl a Venetian blind mounted in place in a window frame by mountings embodying my invention; Fig. 2 is a larger-scale longitudinal verticall section taken substantially on the lines 2--2 of Figs. 3 and 4,`through the end of the header bar and mounting shown at the 0 right in Fig. 1; Fig-3 is a plan of the headerbar end and mounting of` Fig. 2, with the supporting bracketshown i-nhorizontalsection; Fig. 4 is a transverse vertical section onfy the line 4--4 of Fig. 2; Fig. 5 is an isometric view of one form of 25 supporting bracket, with the locking spring in normal locking position; and Fig. 6 is a similar isometric view of a slightly modified form of supporting bracket, with the locking spring pressed back into releasing position.

The Venetian blind per se may be of any conventional type having a headerbar .IIL That header bar is usually provided with a pair of depending brackets II between which is mounted a rockable top slat I2 from which a. series of lower slats I3 is suspended by the usual laddertapes I4. The usual lifting cords l5 extend upward from the bottommost slat through holes in the slats labove itinto the header bar Ill, and

. along such header bar. over suitable pulleys I6 and conveniently through a suitable locking mechanism I1 near one end of the header bar and thence downwardto a convenient point for manipulation. A suitable rockingcord I8 operates any convenient mechanism mounted on one of the brackets to rock the top slat 2, and thereby through the action of the ladder tapes I4 to rock the other slats of the Venetian blind. All

y these may be of any conventional or desired cont struction.

Each end of the header bar I0 is releasably in accordance with my invention., .That supporting bracket 20 isV shown in detail in Figs. 5

and 6.` The type of bracket shown in Fig. G'may 55 readily be converted into the type shown in Fig. 5

mounted in a supporting bracket 20, constructed f by sawing 01T one end of the former', as will lreadily be apparent by comparing the two iigures. 'I'hus only one set of dies is necessary, and indeed only the type of bracket shown in Fig. 6 because it can so readily be connected into the othertype. The supporting brackets 20 are made of sheet metal. Each bracket has a vertical end-wall 2|, which is .in line with the header bar I6 and beyond its end; and a bottom horizontal iiange or ledge 22 which projects from the lower edge of the vertical end-wall 2| and underlies and supports the header-bar end. Each bracket also desirably has a top horizontal flange 23, which projects from the upper edge of the vertical end-wall 2| land overlies the header-bar end and may serve as an attaching flange. In addition, in the type of bracket shown in Fig. 6, the vertical end-wall 2| has an extension 24 toward the rear, and that extension is provided 4with a vertical flange 25 which may also serve as'an attaching flange. It is by omitting the extension 24 and vertical flange 25, or removing them as by sawing, that the type of bracket shown in Fig. 6 is converted into the. type of bracket shown in Fig. 5. v

The vertical end-wall 2|, the top horizontal ange 23, and the vertical flange 25 are all desirably provided with holes 26 for receiving attaching screws 21, to permit the attachment of the bracket 2|) to the associated frame 28, as of a window, by any of those parts as required by the character of such frame; and the bottom horizontal ilange 22 is desirably provided with holes 29to permit the passage of a screw-driver for cooperation with the heads of any screws 21 that may be put through the holes 26 in the top horizontal ange 23. This permits a convenient mountingof the bracket in any of various types of frame 23, as conditions require.v

Each bracket 20 is provided with a leaf-spring 30, which is suitably mounted at or near the top of the vertical end-wall 2| `on the inner face thereof and projects downward through an opening 3| in the bottom horizontal flange or ledge 22. The lower end of this leaf-spring isdesirably provided with a' thumb piece 32, -oi convenient shape. The leaf-spring tends by its resilience to spring away from thevertical wall 2|, into the locking position shown in Figs. 1, 2. 3, -and 5; but may be pressed back against such end wall, as is shown in Fig. 6, by pressing against the thumb piece 32.

Desirably the leaf-'spring 30 enters a recess in the end-wall 2| whenit is pressed back to the position shown in Fig. 6. That recess is conveniently provided by a ller plate 35 which is suitably fastened, as by spot-welding 36, against the inner face f vsuch end-wall 2| and is of a general inverted U-shape to provide that recess betweenl its two legs. The cross-bar of that flller plate 35 may serve to clamp the xed end of the leaf-spring in place, as is clear from'Fig. 2. 'I'he filler plate is conveniently provided with notches 31 around the screw-holes 26 in the vertical end-wall 2l, to receive the screw-heads so that they will not project into the path of and interfere with the movement ofthe header bar l0 when the latter is put into or taken out of place.

Each end of the header bar 20 is provided with a vertical notch 40 lfor receivingV the leaf-spring 30 when the latter springsinto its normal position of Figs'. 1, 2, 3, and 5. The notches 40`may be of any desired extent lengthwise of the header bar; such as the shallow notch 40 shown at the left-hand end in Fig. 1, or the deep notch 40 shown in Figs. 1, 2, and 3 at the right-hand end and also containing one of the pulleys I6 and the locking mechanism Il.

After the brackets 20 are mounted in place in the frame 28, such as a Window frame, the complete Venetian blind as a unit may readily be slipped into place in said brackets, one end at a time if desired, by merely pressing back the leafsprings 30 and sliding theheader bar Il) into the two brackets 20. 'I'he header bar is held in place in such brackets by the entry of the leaf-springs 30 of the two brackets 20 into the notches 40 when Athe header bar Ill is fully in place and said leafsprings are released to spring to their normal position. To remove the Venetian blind, it is merely necessary to press back the two leafsprings 30, by pushing with the finger against their respective thumb-pieces 32, and then to slide the header bar forward out of the brackets 20.
